Windows very slow repsonse with mapped drives. –

Mapped drives
Microsoft Windows XP
I manage a network of around 50 computers. Two of these systems are VERY slow in bringing up a Windows explorer window that also has mapped drives (the window opens and is blank for 30-40 seconds then fully populates with all mapped and local drives). The other computers on the network seem to be able to open these drives, and their files, with little or no delay. If I double click a Word document (or Excel document...) on a mapped drive, it takes a LONG time to open. If I use the File>open command in Word, the file opens with little delay. We are using Office 2000 installed on each machine. The server is Windows Server 2003. The OS on all user machines is Win XP Pro I beleive the problem is related to the OS as opposed to any particular application (though at this point I could believe there are evil gnomes inside the machine giglling madly at the frustration they are causing me...) These were fixes I found on other sites.: I've already shut off drive indexing, and unchecked the DDE setting on the file types tab in the advanced file types control panel (though it does not STAY unchecked...). The set up for various tabs on the extensions/ file type etc is the same on the SLOW machines as it is on the machines un affected by the problem (as far as I've checked anyway). I've done virus/spyware scans, registry cleanings, and even a defrag but with no improvement. Any suggestions would be appriciated.

See this similar


I changed the duplex setting on the card from “auto detect” to Half Duplex/100. That seemed to fix one of the machines (it is an older system and I think the driver might not be an exact match to the card).
No luck on the other one so far.


I have a completely similar situation that I am working on finding a resolution for.

its not a DNS issue because it is limited to this machine, the machine can log on to the domain easily, and it can ping the servers by IP, and FQDN.

The funny thing is that in safe mode with networking, everything works like it should. logging on normally will exhibit the very slow response from the mapped drives.

have you tried that? That would rule out duplex settings as a possibility. it would also point the problem toward a service or process that is running normally but does not run in safe mode with networking.


Some Progress….

An old server was removed from the rack (WIN 2000 Server) This server was used as a license server for a drafting package that we no longer use. The affected system did NOT have this drafting package installed on it, but the server removal is was what caused the issue on affected system, As far as I can tell there are no drives on the affected system mapped to this server. When I re-connected the server to the network, the problem went away. Any Ideas where to look (probably in the registry) I checked the HKEY_CURRENT_USER/network entries and all of those are valid mapped drives. Regardless, the problem is connected with what I had thought was an un related server, so I have a better idea what I’m looking for.

Updates (and hopefully success!) will follow…..


I searched though the registry for any references to the old server name. There was a program that did not uninstall cleanly and had left a few keys in the registry containing the server name . I deleted those keys and the computer is running well! I was surprised that the registry scan software did not find these, but I’ll take it as a win, thanks to all who helped!

    Can you move the problem PC to another network jack (temporarily)? That should rule out cabling and/or port issues. Try enabling WINS as another test

    Another issue may, be that machines need to be cleaned up and defragged, This can cause Window's Explorer to run very slowly as it is digging through a huge amount of history to display current status.
